When a young female sex surrogate is found dead in Portland's Rose Garden, the S.C.U. investigates what could be a crime of lust, rage, passion or possibly even love. Meanwhile, Backstrom receives very upsetting news about his mother.

Backstrom and the S.C.U. are plunged into the zany, provocative world of a performance art festival when one of the participating artists is found dead. Their investigation turns up a slew of potential killers, all of whom are creative types involved in the festival. In the process of solving the murder, Backstrom reveals a surprising appreciation for visual artwork, and a moment of passion between him and a fiery suspect turns into its own piece of performance art.

Backstrom comes home to find Dante Trippi, Valentine's abuser, murdered on his doorstep. Worried that Valentine could be next, the S.C.U.'s investigation leads Backstrom to a ring of counterfeit wine smugglers, a corrupt river patrol cop and a Club of Portland government official. Meanwhile, Valentine's inability to tell the truth makes it harder for the team to catch the killer and Amy has a new boyfriend, of whom Backstrom is not fond,.
